1. What is Curtain Fullness?

Curtain fullness refers to the ratio of fabric width to rod width, determining how gathered or pleated the curtains will be. Proper fullness creates elegant folds and ensures the curtains hang beautifully when closed.

2. How Does the Calculator Work?

The calculator uses the fullness formula:

Where:

• Fabric width — Total width of the curtain fabric (inches)
• Rod width — Width of the curtain rod (inches)

Explanation: The ratio indicates how much fabric is used relative to the rod length. Higher ratios mean more gathered, fuller curtains.

3. Importance of Fullness Calculation

Details: Proper fullness is essential for achieving the desired aesthetic effect. Standard fullness ratios are typically between 1.5 (light gathering) to 3 (very full).

4. Using the Calculator

Tips: Measure both the fabric width and rod width accurately in inches. Enter both values to calculate the fullness ratio.

5. Frequently Asked Questions (FAQ)

Q1: What is a good fullness ratio?
A: For standard curtains, 2-2.5 is common. For sheer curtains, 2.5-3 provides better light diffusion.

Q2: How does fullness affect curtain appearance?
A: Higher fullness creates more folds and a richer look, while lower fullness appears flatter.

Q3: Does fullness affect functionality?
A: Yes, proper fullness ensures curtains stack back neatly when opened and close without gaps.

Q4: How do I measure fabric width?
A: Measure the total width of the curtain panel(s) before any pleating or gathering.

Q5: Should I account for pattern repeats?
A: Yes, when working with patterned fabric, you may need extra width to match patterns at seams.
